Motta, Marcus Vinicius Lisboa published the artcileThermal and spectroscopic analyses of guar gum degradation submitted to turbulent flow, Synthetic Route of 59-23-4, the main research area is guar gum oxidative degradation turbulent flow thermal spectroscopy analysis; (13)C NMR; Drag reduction; Guar gum.
In this paper, a 400 ppm aqueous solution of guar gum polysaccharide was submitted to a turbulent flow regime in order to monitor mol. degradation and drag reduction Guar gum samples were isolated and analyzed by spectroscopic, thermoanal. and viscosimetric techniques. The drag reduction promoted by guar gum is compromised as the polysaccharide undergoes degradation Viscosimetric anal. of guar gum showed a reduction in viscous mol. mass. Mid-IR spectra and hydrogen NMR suggest that mech. degradation promotes hydrolysis of the glycosidic bond α(1→ 6) releasing (D)-galactose owing to the appearance of the carbonyl functional group. Thermal anal. revealed the reduction of the polysaccharide′s thermal stability by reduction of the polymer chain. A comprehensive anal. of these combined parameters affords a foundation for the development of more efficient biopolymers in the context of improved drag reduction
